Unconditional Success
Before I forget it completely, I have to post a link to Nick Williams’ Unconditional Success. This book is outrageously funny. We kept a copy on our desk and would open it at random pages to reinvigorate the team spirit.

Gog Magog Walk
Today Arne and I ventured out to explore rural England. We did the Gog Magog Walk from Arne’s “Walks around Cambridge” guide. The first thing that caught my attention was this chair: Another typical feature of the English landscape is the open fuse box: Also we learnt what a copse is: And more importantly that…

Want to use a Mock?
You are wrong! Well in most cases. It seems above the intellectual means of most agile developers (the non-agile developers don’t write tests) to realize that tests like the following are useless and even harmful. It is not giving me anything apart from test sclerosis. [Test] public void ShouldGetAllByauthorId() { //given var mockRepository = MockRepository.GenerateMock();…

Selenium
A warning to myself, as I forgot over the last year and might forget again. Selenium is bloody slow. Selenium produces crappy error messages.
